More than a quarter of a million residents were evicted – with prejudice – from a Tucson, AZ, assisted living facility recently. You might say it was part of a big sting operation.

After four landscapers suffered stings, bee removal experts discovered a 400-pound hive in the building’s third-story roof. Pest control experts said that Africanized killer bees had been building the hive for at least three years.

It took two bee removal specialists about seven hours to remove the bees, a representative from AAA Africanized Bee Removal told McKnight’s on Friday. The hive was spread over nine square feet under the building’s roofing tiles. Two other firms reportedly declined to take on the job.

Other than the landscapers’ few stings, there were no reports of injuries at the facility, which the bee removal company and local news outlets declined to identify.
